Note

Medium Risk
Removes the --quiet global flag and the pcio output shim, which is a CLI-breaking interface change and may subtly alter stdout/newline behavior for scripts relying on previous output suppression or formatting.

Overview
Removes the custom pcio I/O wrapper and standardizes CLI output on fmt/os.Stdout. All commands/presenters that previously printed via pcio now write directly to stdout/stderr and use fmt.Errorf for errors.

Drops global --quiet support. root no longer wires a quiet option, the pcio package is deleted, spinner output is routed to os.Stdout, and test helpers that silenced pcio output (plus several per-package TestMains) are removed/updated accordingly.

JSON output missing trailing newline in two commands

Medium Severity

The old pcio.PrintJSON used fmt.Fprintln which appends a newline. These two call sites replace it with fmt.Fprint(os.Stdout, json) which does not append a newline, while every other replacement in the PR correctly uses fmt.Println(json). Since text.IndentJSON doesn't include a trailing newline, api-key describe --json and api-key update --json will output JSON without a final newline, breaking piping to tools like jq and causing the shell prompt to render on the same line as the output.
